1 Claim. g 1

This invention relates to a ventilator construction and more particularly ,to a simple and inexpensive louver which can be quickly and easily attached to a wall or chassis to provide optimum ventilation.

The louvers now in use are either integral with the walls which they ventilate or are attached to the walls. The integral louvers are usually formed in a stamping operation and are disadvantageous in that they are expensive to make and cannot be adjusted to provide optimum ventilation under varying conditions. The attachable louvers now in use are relatively complex and expensive and cannot be easily standardized. They require an expensive die for every given area of opening.

This invention provides a louver construction which is simple and inexpensive and which can be easily attached to a wall or chassis. The louver is adapted to be attached in a number of different ways to the wall or chassis so as to provide optimum ventilation as well as optimum weather protection under all conditions. The louver is suitable for use with a considerable number of apertures of different sizes.

An object of the invention is to provide a louver which can be quickly attached to a wall to furnish ventilation.

Another object of the invention is to provide a louver of the above character which can be easily standardized in a few difierent sizes so that the louver can be purchased by the linear foot in the size desired.

A further object is to provide a louver of the above character which can be fastened to a wall in a number of different positions so as to furnish a maximum amount of protection against different weather conditions.

Still another object is to provide a louver which can be simply and inexpensively constructed.

Other objects and advantages will be apparent from a detailed description of the invention and from the appended drawings and claim.

In the drawings:

Figure 1 is a front elevational view of a wall before the louvers are attached;

Figure 2 is a front elevational view of the proposed louver;

Figure 3 is an enlarged sectional view of the louver taken substantially on the line 2--2 of Figure 4; and

Figure 4 is a perspective view from in front and above the wall, showing the louvers attached to the wall.

In one embodiment of the invention a wall is provided. The wall has spaced cross strips !2 which define apertures M. Spaced holes it are provided in each of the cross strips 12.

A plurality of louvers, generally indicated at It, are adapted to be secured to the cross strips l2. Each of the louvers [8 has a plurality of flat heads 20 spaced at the same intervals as the cross strips l2. Each head 20 has a hole 22 and a rivet 24 extends through each hole 22 and the corresponding hole It in the cross strips [2 to secure the louver to the wall I0. The flat heads 20 of each louver are integrated with each other by a flat band 26 which extends in a transverse direction to a position above the heads 20. An ofiset portion 28 integral with the band 26 extends from each band at an angle such as 45. Each oifset portion 28 is in turn bent inwardly to form a lip 30 substantially parallel to the head 20 and the band 26. The lips 30 extend in a transverse direction to a position above the head 20 to provide one side of each head with a projecting portion.

The louvers are secured to the wall ill in parallel relationship to one another, with the offset portions 28 being positioned adjacent the apertures M. The louvers are preferably secured to the wall in abutting relationship, such that the portion projecting from each flat head 20 fits into the undercut portion in the corresponding flat head of the adjacent louver. Ventilation for the wall I0 is then provided by the opening between the offset portions 28 on each louver and the flat band 26 on the adjacent louvers.

The louver construction disclosed above has a number of advantages. The louvers can be easily attached to any wall in which the cross strips [2 have substantially the spacing of the fiat heads 20. Thus, the size of the apertures l4 between the cross strips l2 may vary considerably by varying the width of the cross strips. The efiective ventilation can also be varied by varying the height of the apertures I4 and accordingly varying the number of louvers attached to the cross strips.

The louvers may be standardized in a number of difierent sizes, each size having a predetermined spacing between adjacent fiat heads 20. By employing standardized louvers, the louvers may be purchased by the linear foot in the size desired and at a price lower than the louvers now in use.

Depending upon the weather conditions, the louvers may be attached to the inside or outside surface of the wall l 0 and with the offset portions 28 pointing upwardly or downwardly. Since-the louvers may be positioned in accordance with the weather conditions normally encountered in a particular location, they are adapted to provide a maximum amount of protection against such conditions as rain and Wind-blown sand.

Although this invention has been disclosed and illustrated with reference to particular applications, the principles involved are susceptible of numerous other applications which will be apparent to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claim.

What is claimed is:

In combination, a Wall member having an elongated opening intermediate its ends, the wall member also having a plurality of cross strips spaced from one another to provide apertures, there being a plurality of holes in each cross strip, a plurality of louvers extending in spaced parallel relationship across the apertures, each louver including, a plurality of completely fiat heads spaced in accordance with the spacing of the cross strips, there being a hole in each flat head adapted to be aligned with aporresponding hole in its associated cross strip, means extend- 2 ingthrough the holes in the fiat heads and cross 4 strips to attach the louvers to the Wall member, a plurality of fiat bands joining the flat heads, and an ofiset portion extending from each fiat band at a predetermined angle to the flat band to provide a ventilation opening through the Wall, the fiat bands and ofiset portions defining on each fiat head a projection at one side and an undercut at the opposite side to provide an interleaving of the flat heads on the difierent louvers when the louvers are attached 'to the cross strips in abutting relationship.
